Ingredients:
- 1.5 lb top sirloin steak, cut into 1-inch cubes
- 12 oz bowtie (farfalle) pasta
- 2 tbsp neutral oil (grapeseed or avocado oil)
- 4 tbsp unsalted butter
- 6 cloves garlic, minced
- 1 cup heavy cream
- 0.5 cup freshly grated Parmesan cheese
- 0.5 cup reserved pasta cooking water
- 0.25 cup fresh Italian flat-leaf parsley, chopped
- 2 tbsp fresh chives, finely snipped
- 1 tsp lemon zest
- Salt and black pepper to taste
Instructions:
- Bring a large pot of heavily salted water to a boil. Add the bowtie pasta and cook for approximately 1 minute less than the package instructions for al dente texture. Reserve 1/2 cup of the starchy pasta water before draining.
- While pasta boils, pat the steak cubes completely dry with paper towels. Season generously on all sides with salt and black pepper.
- Heat a large cast-iron skillet over high heat with 2 tablespoons of neutral oil. Once the oil is shimmering and just smoking, add the steak bites in a single layer. Sear for 2-3 minutes without moving to develop a dark brown crust, then toss to brown the remaining sides. Remove steak from the pan and set aside.
- Reduce heat to medium. Add the butter to the same skillet, scraping the bottom with a wooden spoon to loosen the browned steak bits (the fond). Add the minced garlic and sauté for 1 minute until fragrant.
- Pour in the heavy cream and whisk continuously. Bring to a gentle simmer. Stir in the Parmesan cheese and the reserved pasta water, whisking until the sauce is smooth and emulsified.
- Add the cooked pasta and steak bites (along with any accumulated juices) back into the skillet. Toss for 1-2 minutes until the sauce thickens and coats the pasta.
- Remove from heat. Garnish with fresh parsley, chives, and lemon zest. Serve immediately.
